Application filed January 25, 1926. Serial No. 83,536.

The object of myinvention is to produce a cheap, efiective and easily installed device by means of which Window sash having no counterweights may nevertheless be retained in various positions in the window frames.

The accompanying drawings illustrate my invention. Fig. 1 is a front elevation of a pair of window sash equipped with my invention; Fig. 2 a transverse vertical section of a fragment of a window sash and adjacent casing, with my improved device in a side elevation; Fig. 3 a vertical section on line 33 of Fig. 2, and Fig. at a side elevation in partial longitudinal section of a slightly modified form of my invention.

In the drawings 10 indicates a metal frame conveniently about inch wide, inch deep and 6 or 8 inches long, with rounded ends, separated parallel sides, cross braces 11, and spring platforms 12, one at each end.

Journaled in frame 10, one near each end,

are two wheels or rollers 13, 13, each of which may be conveniently journaled by means of short threaded pins 14, having smooth outer ends cross-slotted, said pins being threaded into the wheel and the outer ends journaled in suitable perforations in the side walls of frame 10.

Attached, by bolts 15, 15, to the spring platforms 12, are the two ends of a spring 16 arched at its middle so as to form two con tact points 17, 17, the construction being such that, in spite of the fact that both ends of the spring are firmly anchored, the contact points 17, 17, upon the application of suitable pressure to frame 10, may be brought nearer to frame 10, the arch 16 being by such pressure temporarily increased in curvature.

The structure. which has been described is intended to be seated in a pocket 18 formed in one of the stiles of a window sash 19, the depth of such pocket being such that the peripheries of rollers 13 will, with the spring 16 unstressed, project some distance beyond the face of the stile. The contact points 17 may, if desired, rest directly upon the bottom of the pocket 18, but I prefer to provide a wear plate 20 mounted in the bottom of the pocket by screws 21.

For especially heavy sash, or for other reasons, it may be desirable to have a spring which would be somewhat stifi'er than could be practicably obtained by the use of a strip of flat metal and for this purpose the spring may be longitudinally ribbed as indicated at 22 in Fig. 4..

By anchoring both ends of spring 16 on the frame 10, the spring will act uniformly throughout the length of the frame 10 and danger of improper loosening of the parts is avoided.

The device, by reason of its rounded ends permits the formation of pocket 18 by means of ordinary bits and chisels, any ordinary giarpenter being able to make a nice working In operation pocket 18 will be made of such depth that, when the parts are assembled as shown in the drawings, spring 16 will be stressed enough to exert an amount of pressure, through rollers 13, upon the sash and casing 23 that the weight of the sash will be held at any desired point of elevation in the casing, a rolling of the rollers 13 permitting easy movement of the sash by application of a force on the sash either up or down.

A standard lock washer 25 maybe arranged between the inner ends of the two screws 14 and said screws set down hard on the washer so that they will be held againstaccidental unscrewing.

I claim as my invention 1. A sash holder comprising a main body, a pair of rollers, the peripheries of which pro ect from one face of said body, and a bowed supporting spring projecting from the opposite face of said body, said spring having both ends anchored to the body and reversely arched at its middle to form two separated contact points intermediate of the length of the main body with an intermediate bow free from the said body.

2. A sash holder comprising in a unitary structure a hollow frame having sides and end members, a pair of rollers mounted within the frame, one at each end thereof and having their peripheries projecting from one side of the frame, ears on the opposite ends of the frame and extending towards one another, a spring reversely arched at its middle to form two separated contact points intermediate of the length of the main body with an intermediate bow free from the frame and having its ends secured to said ears;

I 3. A sash holder comprising a main body, a pair of rollers, a pair of threaded axle pins threaded into each roller and having smooth outer ends, a lock washer arranged between and abutted by the inner ends of said pins, perforations in the side Walls of said main body for receiving the outer ends of said pins and supporting the rollers so that the peripheries thereof will project from one face of the body, and spring means carried by the body and adapted to yieldingly support the same against a force applied to the exposed peripheries of the rollers.

In Witness whereof, I have hereunto set FRANCIS HOVVARD STOWELL.
